This page used to test IDMFitter.LMFit()
Unlike TestLMFit.htm, it uses VBS class for
analytically defined function and partial derivatives
instead of string expression parsing.
Parameters fixed: P0=0.3, P2=-0.35.
Following expression will be fitted:
Y(X)=0.123+3.456*X-0.345*X2+0.00567*X3
Use Fitting Options
Fix P0 and P2
Add random noise
